3 Baseline 10/100 Switch 48-Port
10BASE-T/100BASE-TX plus 2-Port Gigabit is a versatile, easy-to-use
unmanaged switch. It is ideal for users who want the high-speed per-
formance of 10/100 switching with the added functionality of two
Gigabit links, but do not need sophisticated management capabilities.
This Baseline Switch is shipped ready for use; no configuration is nec-
essary.
The Baseline Switch has 48 shielded RJ-45, 10/100 Mbps
auto-negotiating ports and two shielded RJ-45, 10/100/1000BASE-T
ports on the front panel. Each port automatically determines the
speed and duplex mode of the connected equipment and provides a
suitable switched connection. Each port also supports automatic
MDI/MDI-X detection.
The Baseline Switch is suited for office use where it can be free
standing, or rack mounted (in a wiring closet or equipment room).
The Baseline Switch comes with:
One power cord
Four self-adhesive rubber pads
One mounting kit
The Baseline Switch provides high performance switched connections
to 10 Mbps and 100 Mbps hubs, servers and workstations that need
a dedicated switched link and two 10/100/1000 BASE-T ports that
can connect to other 10/100/1000 BASE-T ports or servers and
workstations.

48 RJ-45 10/100 Ports and 2 RJ-45 10/100/1000 BASE-T Ports
WARNING: RJ-45 ports. These are shielded RJ-45 data
sockets. They cannot be used as standard traditional tele-
phone sockets, or to connect the unit to a traditional PBX or
public telephone network. Only connect RJ-45 data connec-
tors, network telephony systems, or network telephones to
these sockets. Either shielded or unshielded data cables with
shielded or unshielded jacks can be connected to these data
sockets
AVERTISSEMENT: Points d’accès RJ-45. Ceux-ci sont pro-
tégés par des prises de données. Ils ne peuvent pas être util-
isés comme prises de téléphone conventionnelles standard, ni
pour la connection de l’unité à un réseau téléphonique cen-
tral privé ou public. Raccorder seulement connecteurs de
données RJ-45, systèmes de réseaux de téléphonie ou télé-
phones de réseaux à ces prises. Il est possible de raccorder
des câbles protégés ou non protégés avec des jacks protégés
ou non protégés à ces prises de données.
VORSICHT: RJ-45-Porte. Diese Porte sind geschützte Dat-
ensteckdosen. Sie dürfen weder wie normale traditionelle
Telefonsteckdosen noch für die Verbindung der Einheit mit
einem traditionellem privatem oder öffentlichem Telefon-
netzwerk gebraucht werden. Nur RJ-45-Datenanscluße, Tele-
fonnetzsysteme or Netztelefone an diese Steckdosen
anschließen. Entweder geschützte oder ungeschützte Buch-
sen dürfen an diese Datensteckdosen angeschlossen werden.
10BASE-T/100BASE-TX Ports
The Switch has 48 auto-negotiating 10BASE-T/100BASE-TX ports con-
figured as Auto MDIX (cross-over). These ports automatically detect
whether they need to operate in MDI or MDIX mode. Each ports
speed and duplex mode (half duplex or full duplex) is automatically
determined by the capabilities of the connected device. The maximum
segment length is 100 m (328 ft) over Category 5 twisted pair cable.
CAUTION: The Baseline Switch supports full duplex
auto-negotiation. If the connected device does not support
auto-negotiation, the Switch will operate in half duplex
mode (even if the device is operating in full duplex mode). In
such a configuration, you may notice some degradation of
network performance. 3Com recommends that you use
devices that are capable of auto-negotiation (and that you
ensure that auto-negotiation is enabled, if it is a configurable
option).
10/100/1000BASE-T Ports
The Switch has two auto-negotiating 10/100/1000BASE-T ports con-
figured as Auto MDIX (cross-over). These ports automatically detect
whether they need to operate in MDI or MDIX mode. These ports
provide 10/100/1000 Mbps full duplex connections to other Gigabit
Ethernet devices. Full duplex allows packets to be transmitted and
received simultaneously which, in effect, doubles the potential
throughput of a link. These ports require either straight-through or
cross-over Category 5 cables with RJ-45 connectors at both ends. The
maximum UTP cable length is 100 m (328 ft) over Category 5 cable.
The 10/100/1000BASE-T ports will auto-negotiate to the appropriate
speed.
Priority Queuing
The Switch offers priority queuing, meaning all packets that are
received are examined to see if they have been priority encoded. If a
packet has been, then the Switch will read the priority level and
determine whether the packet should be directed through the normal
or high priority channel. This feature can be useful for example during
excessive loads when one type of traffic may require priority over
another. The Switch is configured to comply with 802.1p, VLAN
tagged frames.
The traffic prioritization feature supported by the Switch is
compatible with the relevant sections of the IEEE 802.1D
standard (incorporating IEEE 802.1p).
Traffic prioritization ensures that high priority data is forwarded
through the Switch without being delayed by lower priority data. It
differentiates traffic into classes and prioritizes those classes
automatically. Traffic prioritization uses the multiple traffic queues that
are present in the hardware of the Switch to ensure that high priority
traffic is forwarded on a different queue from lower priority traffic,
and is given preference over that traffic. This ensures that
time-sensitive traffic gets the highest level of service. The 802.1D
standard specifies eight distinct levels of priority (0 to 7), each of
which relates to a particular type of traffic. The priority levels and
their traffic types are shown in the following table.
Connecting to a Network Device
To connect a device to the Baseline Switch, use Category 5
unshielded or shielded (screened) 100 Ohm TP cable (or Category 3
cable for a 10 Mbps connection). The maximum length of cable for
each connection is 100 m (328 ft). Connect one end of the cable to
an RJ-45 port on the Baseline Switch, and the other end to the
appropriate RJ-45 port on the connecting device.

Connecting to another Switch or Hub
If you connect two Baseline Switch units together, 3Com rec-
ommends that you use the 10/100/1000BASE-T ports on
both units for the link. You must use Category 5 cable when
connecting the units.
10/100/1000BASE-T connection:
To connect a Baseline Switch to
another Switch using the 10/100/1000BASE-T port, use a normal
‘straight through’ or ‘cross-over’ cable and connect each end to the
10/100/1000BASE-T port on each unit.
100BASE-TX connection:
The Baseline Switch can be connected to a
SuperStack 3 hub using either a normal ‘straight through’ or a
‘cross-over’ cable. Connect any port on the Baseline Switch to any
port on the hub, as shown below. The ports on the Baseline Switch
are configured as auto-MDI and will automatically detect whether
they need to operate in MDI or MDIX mode.

Power Supply
The Baseline Switch automatically adjusts to the supply voltage. Only
use the power cord that is supplied with the unit.
7
Self-adhesive Pads
The unit is supplied with four self-adhesive rubber pads.
You do not need to apply the pads if you intend to rack
mount the unit.
If the unit is to be part of a free standing stack, apply the pads to
each marked corner area on the underside of the unit. Place the unit
on top of the lower unit, ensuring that the pads locate with the
recesses of the lower unit.
Positioning the Switch
When deciding where to position the Baseline Switch ensure:
It is accessible and cables can be connected easily.
Cabling is away from sources of electrical noise. These include lift
shafts, microwave ovens, and air conditioning units. Electromag-
netic fields can interfere with the signals on copper cabling and
introduce errors, therefore slowing down your network.
Water or moisture cannot enter the case of the unit.
Air flow around the unit and through the vents in the side of the
case is not restricted (3Com recommends that you provide a min-
imum of 25 mm (1 in.) clearance).
The air is as free from dust as possible.
Temperature operating limits are not likely to be exceeded. It is
recommended that the unit is installed in a clean, air conditioned
environment.
It is always good practice to wear an anti-static wrist strap
when installing network equipment, connected to a ground
point. If one is not available, try to keep in contact with a
grounded rack and avoid touching the unit's ports and con-
nectors, if possible. Static discharge can cause reliability
problems in your equipment.
Rack Mounting or Free Standing
The unit can be mounted in a 19-inch equipment rack using the
Mounting Kit or it can be free-standing. Instructions for fitting the
Mounting Kit are on page 4. Do not place objects on top of the unit
or stack.
CAUTION: If installing the Baseline Switch in a free standing
stack of different size SuperStack 3 units, the smaller units
must be installed above the larger ones. Do not have a free
standing stack of more than six units.
Power Supply
Power problems can be the cause of serious failures and downtime in
your network. Ensure that the power input to your system is clean
and free from sags and surges to avoid unforeseen network outages.
We recommend that you install power conditioning, especially in
areas prone to black outs, power dips and electrical storms.
The unit is intended to be grounded. Ensure it is connected to earth
ground during normal use. Installing proper grounding helps to avoid
damage from lightning and power surges.

.
3
Connect the plug to the power supply outlet socket and switch
on the power supply at the socket.
When the switch is powered on, the Power LED should stay lit.
Spot Checks
At frequent intervals you should visually check the Baseline Switch.
Regular checks can give you an early warning of a possible failure;
any problems can then be attended to when there will be least effect
on users. Check the following:
If you experience any problems operating the Baseline Switch, refer to
“Problem Solving” on page 4.
Introduction
The Baseline Switch is supplied with two mounting brackets and four
screws. These are used for rack mounting the unit. When mounting
the unit, you should take note of the guidelines given in “Positioning
the Switch” on page 3.
Rack Mounting the Units
The Baseline Switch is 1U high and will fit a standard 19-inch rack.
CAUTION: Disconnect all cables from the unit before con-
tinuing. Remove the self-adhesive pads from the underside
of unit, if already fitted.
1
Place the unit the right way up on a hard, flat surface with the
front facing towards you.
2
Locate a mounting bracket over the mounting holes on one side
of the unit.
3
Insert the two screws supplied in the mounting kit and fully
tighten with a suitable screwdriver.
4
Repeat the two previous steps for the other side of the unit.
5
Insert the unit into the 19-inch rack and secure with suitable
screws (not provided).
6
Reconnect all cables.
Refer to the information about LEDs given earlier in this guide to see
if the problem can be identified and rectified. Here are some common
problems that can occur:
Link Status LED not lit for a port that has a connection.
There is
a problem with this connection. Check that:
The device being connected to is powered on and operating cor-
rectly.
The cable is connected at both ends.
The cable is not damaged.
If the connection is to a workstation, that the workstation’s net-
work interface is installed and configured correctly.
All Link Status LEDs appear to be lit continually.
There may be
broadcast storms on the network. Remove port connections one at a
time, waiting a few seconds between each port. If the LEDs go off
after removing a port connection, the device that was connected to
that port is introducing an excessive amount of broadcast frames to
the network (some pieces of network equipment operate by sending
out broadcast frames regularly). Refer to the documentation that
accompanies the device for information on disabling the broadcast
operation.
The Fan Alert LED is flashing amber.
This indicates that one or
both of the internal fans are operating in a non-optimal mode. The
fan(s) may be turning at a lower than expected speed, or may have
stopped turning. Power the unit off and on again.
If any of these problems persist and the unit still does not operate
successfully, contact your supplier with the following information
before returning the unit:
Product number and serial number (printed on a label supplied
with the unit)
